MRCOOL DIY Mini Split - 21,000 BTU 2 Zone Ductless Air Conditioner and Heat Pump with 25 ft. and 35 ft. Install Kit, DIYM218HPW01C08

Imagine delivering unmatched comfort to your customers’ homes or businesses with a system that’s as easy to install as it is powerful. The MRCOOL DIY Mini Split 21,000 BTU 2 Zone system is designed for business owners and contractors who demand efficiency, reliability, and simplicity—without sacrificing performance. This isn’t just another HVAC unit; it’s a game-changer that transforms how you work and what you offer your clients.

Effortless Installation Saves Time and Money

Say goodbye to complicated installs that drain your resources. MRCOOL’s patented Pre-Charged Quick Connect Line Sets revolutionize the installation process. These line sets come pre-filled with refrigerant, so there’s no vacuuming or refrigerant charging needed. This means you can confidently install the system yourself or with your team, cutting down on labor time and expensive technician fees. The included coupler kit extends reach effortlessly, allowing you to cover larger or more complex spaces without hassle.

Powerful, Efficient, and Built to Last

At the heart of this system is an 18,000 BTU condenser that delivers exceptional energy savings with a 21.2 SEER2 and 8.6 HSPF-5 rating. Your customers will enjoy year-round comfort, with heating that performs reliably even when temperatures plunge to -13°F. The Gold Fin® coating protects the condenser from corrosion, especially in coastal or harsh environments, ensuring the system stays durable and dependable for years to come. Backed by a 7-year compressor warranty and a 5-year parts warranty, this system offers peace of mind alongside performance.

Tailored Comfort for Every Space

This 2-zone system includes two versatile air handlers: a 9,000 BTU unit perfect for smaller rooms (180-375 sq. ft.) and a 12,000 BTU unit designed for medium-sized spaces (376-500 sq. ft.). Both units offer multiple modes—COOL, HEAT, AUTO, DRY, and SLEEP—so your customers can customize their comfort no matter the season. The compact, lightweight design means installation is fast and stress-free. Plus, with SmartHVAC app compatibility, users can control their environment remotely, enhancing convenience and satisfaction.
